The details: Researchers from the University of Montreal studied the brain activity of newborns from two groups of new mothers. One group exercised at a moderate level for 20 minutes at least three times a week while they were pregnant; the other group didn’t work out at all during pregnancy. When all the babies’ brains were tested, the researchers discovered that the cognitive activity of the babies whose mums broke a sweat was more fully developed.
The study authors aren’t sure if the brain boost lasts past the infant stage; they’re currently testing older babies to find out. But it’s smart advice if you’re currently knocked up—or you plan to pop out a kid in the near future. Add it to the list of other reasons why working out is good for mum and baby: moderate exercise eases backaches, lowers the risk of pregnancy-related diabetes, and can help you sleep better. For baby, it’s linked to decreased odds of obesity.
